Documentation unclear on what shape() array argument does

[createthis]

Describe the bug The documentation for the shape() method shows an Array argument: https://github.com/jquense/yup#objectshapefields-object-nosortedges-arraystring-string-schema

However, it doesn't say what it does or how it should be used.

There are a couple of issues that mention it in regard to Cyclic Dependency errors:

• https://github.com/jquense/yup/issues/1561
• https://github.com/jquense/yup/issues/1006

Is the purpose of the array argument to avoid Cyclic Dependency issues? How does that work?

Expected behavior It would be nice to have this Array argument documented.
